Answer

$9.3 \times 10^{7}$ $5.3 \times 10^{-23}$ $5.97 \times 10^{24}$

Work Step by Step

93 Million = 93,000,000 Move the decimal point over 7 spaces makes the exponent $10^{7}$ thus $9.3 \times 10^{7}$ 0.000000000000000000000053 Moving the decimal point to the right makes the exponent negative. Move it 23 times and you get $5.3\times10^{-23}$ 5,970,000,000,000,000,000,000,000 Move the decimal point over 24 spaces makes the exponent $10^{24}$ thus $5.97 \times 10^{7}$
